Hezekiah's Tunnel & the Siloam Inscription

The Siloam Inscription slab, incised palaeo-Hebrew letters on stone
Wikikati, Public domain — source

Kings ends its account of Hezekiah with an engineer's footnote: he made the pool and the conduit that brought water into the city. The conduit is still there — a winding tunnel chiselled through bedrock from the Gihon spring, which you can wade through today. Deep inside, workers left a short Hebrew text describing the moment the two digging crews, tunnelling from opposite ends, heard each other's picks through the rock and broke through. No king is named; the workmen told their own story.

What this find showsA major eighth-century royal engineering project exactly matching the biblical notice, with a contemporary Hebrew inscription — one of the most secure text-and-spade matches in the entire field.
What it does not proveThe inscription itself names no king, so the attribution to Hezekiah rests on the biblical text plus the dating of the tunnel — a very strong but still inferential chain.
